Code Explanation:

Function Definition:

def replace_a_with_dollar(input_string):

    result = input_string.replace('a', '$')

    return result

The function replace_a_with_dollar takes one parameter: input_string, which is expected to be a string.

Inside the function:

input_string.replace('a', '$') is called, which replaces every occurrence of the character 'a' in input_string with the character '$'.

The modified string is stored in the variable result.

The function returns the modified string (result).

User Input:

input_string = input("Enter a string: ")

The input() function prompts the user to enter a string. The entered string is stored in the variable input_string.

Function Call and Output:

output_string = replace_a_with_dollar(input_string)

print("Modified string:", output_string)

The replace_a_with_dollar function is called with input_string as the argument, and its result is assigned to output_string.

The modified string (output_string) is printed to the console.
